Description:
Horse flies will mistakenly see the centrally placed ball in the H-trap as a large animal and move towards this ball. Once they are positioned on this black ball they will investigate the 'victim' and try to sting it. After this unsuccessful attempt, they will fly away from the trap. Horse flies are vertical risers, they can only fly upwards. The trap is designed in such a way that via a conical hood system, the flies are guided upwards into a centrally placed collecting bin. From this they cannot escape. The bin needs to be emptied periodically. Extensive tests have shown that reductions of 90-95% of horse flies in an area around the trap can be realised.
